This an original pic. It is a bad shot, something to do with the 30+mph wind gusts blowing my 230 lbs. around on top of the 225 lb. rated ladder I guess, but you can see the attachment points.

Looking at the tree from which the far end of the loadlock is string-supported.

Again, not a very good shot, but it will give you a general idea of the L's configuration.
Orientation has the loadlock's free end pointing south.
